Gen Gotanda is the grandfather of Dan Gotanda and Ran Gotanda in the series. He's also owner and head chef of Gotanda Eatery. He's described as being heavy handed on Ichika and Dan but likes to go easy on Ran. Ichika describes him of having big strong arms from spending all day stirring two heavy woks and a healthy tan from the heat of his cooking fire. He's lively as shown when he throws a ladle at Dan hard enough to knock him out of his chair from across the room for arguing with his sister about joining IS academy.
